CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.16/705,861, filed Dec. 6, 2019, which claims benefit of and priority toU.S. Provisional Patent Application No. 62/777,919, filed Dec. 11, 2018,the entire contents of each of which are incorporated by reference intheir entirety.

BACKGROUND

The human eye can suffer a number of maladies causing mild deteriorationto complete loss of vision. While contact lenses and eyeglasses cancompensate for some ailments, ophthalmic surgery may be required forothers. Generally, ophthalmic surgery may be classified into posteriorsegment procedures, such as vitreoretinal surgery, and anterior segmentprocedures, such as cataract surgery. Vitreoretinal surgery may addressmany different eye conditions, including, but not limited to, maculardegeneration, diabetic retinopathy, diabetic vitreous hemorrhage,macular hole, detached retina, epiretinal membrane, and cytomegalovirusretinitis.

For cataract surgery, a surgical procedure may require incisions andinsertion of tools within an eye to replace the clouded natural lenswith an intraocular lens (“IOL”). A large incision site may cause alonger post-operation healing time. To reduce this healing time, typicaloperating procedures have shifted to making incisions of about 2millimeters in size into the eye. While this smaller size of incisionmay reduce post-operation healing time, problems such as the size andfunctionality of the insertion tool may arise as the incision sizecontinues to shrink. Typically, the insertion tool may be pre-loadedwith the IOL that may be inserted into the patient's eye once theclouded natural lens is removed. The insertion tool may include aplunger for forcing the IOL out of the nozzle of the insertion tool. Theplunger may have additional functions including haptic tucking andfolding of the IOL. Once an incision has been made, the insertion toolmay be inserted into the eye through the incision, and the folded IOLmay be dispensed into the eye by actuation of the plunger. As theincision site decreases, the size of the nozzle of the insertion toolmay decrease accordingly.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of thepresent disclosure, reference will now be made to the implementationsillustrated in the drawings and specific language will be used todescribe them. It will nevertheless be understood that no limitation ofthe scope of the disclosure may be intended. Any alterations and furthermodifications to the described devices, instruments, methods, and anyfurther application of the principles of the present disclosure arefully contemplated as would normally occur to one skilled in the art towhich the disclosure relates. In particular, it is fully contemplatedthat the features, components, and/or steps described with reference toone or more implementations may be combined with the features,components, and/or steps described with reference to otherimplementations of the present disclosure. For simplicity, in someinstances the same reference numbers may be used throughout the drawingsto refer to the same or like parts.

The example embodiments described herein generally relate to eyesurgery. More particularly, the example embodiments generally relate tosystems, methods, and devices for inserting an intraocular lens (“IOL”)into an eye. Embodiments may include an insertion tool for preparationand delivery of the IOL into a patient's eye that includes a plunger, anozzle, and a haptic optic management system. In some embodiments, thehaptic management system may fold the IOL and tuck one or more hapticsof the IOL. The haptic extends from an optic of the IOL and stabilizesthe IOL when disposed within the capsular bag of the eye. Afterpreparation of the IOL, the plunger forces the IOL through the insertiontool and out the nozzle.

FIG. 1 illustrates a schematic of an insertion tool 100. In someembodiments, insertion tool 100 may include a drive system 102, aplunger 104, a haptic optic management system (interchangeably referredto as “HOMS”) 106, and a nozzle 108. The drive system 102 may be anysystem or combination of components operable to actuate the plunger 104.For example, the drive system 102 may utilize a lever and/or pneumaticsystems; a manually driven system or component; an electromechanicalsystem; a hydraulic system; or other device operable to drive theplunger 104 to advance; partially advance; or fully deliver an IOL 110from the insertion tool 100. The plunger 104 is coupled to the drivesystem 102. The drive system 102 is operable to actuate the plunger 104.For example, the drive system 102 may be powered by, for example,electrically, mechanically, hydraulically, pneumatically, combinationsthereof, or in some other manner. In response to the drive system 102,the plunger 104 moves through the HOMS 106. The HOMS 106 may be locatedbetween the drive system 102 and the nozzle 108. In alternateembodiments, the HOMS 106 may be disposed at other locations within theinsertion tool 100. In some embodiments, the HOMS 106 may contain an IOL110 in an unfolded position.

The drive system 102 may be any system, component, or group ofcomponents operable to advance an IOL 110 through the insertion tool100. For example, the drive system 102 include plunger, schematicallyshown as plunger 104 in FIG. 1 , that is operable to engage the IOL 110disposed within the insertion tool 100 and advance the IOL 110 withinthe insertion tool 100. In some instances, the plunger 104 is operableto expel the IOL from the insertion tool 100.

In some instances, the drive system 102 may be a manually driven system.That is, in some instances, a user applies a force to cause the drivesystem 102 to operate. An example drive system 102 includes a plunger104 that is manually engageable directly or indirectly by a user to pushthe plunger 104 through the insertion tool 100. When advanced, theplunger 104 engages an IOL 110 and advances the IOL 110 through theinsertion tool 100, which may also include expelling the IOL 110 fromthe insertion tool 100. A non-limiting example of a manual IOL insertiontool is shown in U.S. Patent Application Publication No. 2016/0256316,the entire contents of which are incorporated herein by reference in itsentirety. According to other implementations, the drive system 102 maybe an automated system. Example automated drive systems are shown inU.S. Pat. Nos. 8,808,308; 8,308,736; and 8,480,555, the entire contentsof each being incorporated herein by reference in their entirety. Stillfurther, other automated drive systems within the scope of the presentdisclosure are described in U.S. Pat. No. 8,998,983 and U.S. PatentApplication Publication No. 2017/0119522, the entire contents of eachbeing incorporated herein by reference in its entirety. While exampledrive systems are provided as examples, these systems are not intendedto be limiting. Rather, any component, group of components, systems,devices, mechanisms, or combinations thereof operable to advance an IOL110 is within the scope of the present disclosure.

As shown in FIG. 1 , the IOL 110 is a single piece IOL that includes anoptic 114 and haptics 112 extending from opposing sides of the optic114. For example, in the example IOL 110 shown in FIG. 1 , the haptics112 are disposed 180° relative to each other along an outer periphery ofthe optic 114. However, other types of IOLs are within the scope of thedisclosure. For example, a multi-piece IOL, in which the optic and oneor more haptics are separate components, may also be used.

The IOL 110 may have a shape similar to that of a natural lens of an eye(e.g., eye 200 shown in FIG. 2A). The IOL 110 may be made from anumerous materials including, but not limited to, silicone, acrylic,and/or combinations thereof. Other materials are also contemplated. Thehaptics 112 extend from a periphery of the optic 114 and function tostabilize the IOL 110 when disposed within an eye.

In some instances, the HOMS 106 may be actuated to tuck the haptics 112over the optic 114 and fold the optic 114. For example, the HOMS 106 mayoperate to fold the haptics 112 over the optic 114 and fold the optic114 over or around the folded haptics 112. The IOL 110 is shown in afolded configuration at 116. The folded configuration 116 of the optic114 may involve one or more haptics 112 folded relative to the optic 114and, in some instances, the optic 114 folded relative to one or more ofthe haptics 112. The plunger 104 may be advanced through the HOMS 106once the HOMS 106 has folded the IOL 110. As the plunger 104 movesthrough the HOMS 106, the plunger 104 displaces the folded IOL 110 fromthe HOMS 106. For example, the plunger 104 may force the folded IOL 110into and through the nozzle 108.

FIG. 2A illustrates an eye 200 of a patient undergoing an operation withinsertion tool 100. As illustrated, the insertion tool 100 dispenses afolded IOL 110 into the eye 200 of a patient. In some embodiments, anincision 202 is made in the eye 200 by a surgeon, for example. Forexample, in some instances, the incision 202 may be made through thesclera 204 of the eye 200. In other instances, an incision may be formedin the cornea 209 of the eye 200. The incision 202 may be sized topermit insertion of a portion of the insertion tool 100 in order todeliver the folded IOL 110 into the capsular bag 208. For example, insome instances, the size of the incision 202 may have a length less thanabout 2000 microns (2 millimeters). In other instances, the incision 202may have a length of from about 0 microns to about 500 microns, fromabout 500 microns to about 1000 microns, from about 1000 microns toabout 1500 microns, or from about 1500 microns to about 2000 microns.

After the incision 202 is made, the insertion tool 100 is insertedthrough the incision into an interior portion 206 of the eye 200. Theinsertion tool 100 is actuated to dispense the folded IOL 110 into thecapsular bag 208 of the eye 200. Upon dispensation, the folded IOL 110reverts to an initial, unfolded state, and the IOL 110 settles withinthe capsular bag 208 of the eye 200, as shown on FIG. 2B. The capsularbag 208 holds the IOL 110 within the eye 200 in a relationship relativeto the eye 200 so that the optic 114 refracts light directed to theretina (not shown). The haptics 112 of the IOL 110 engage the capsularbag 208 to secure the IOL 110 therein. After dispensing the IOL 110 intothe capsular bag 208, the insertion tool 100 is removed from the eye 200through the incision 202, and the eye 200 is allowed to heal over aperiod of time.

FIGS. 3-5 illustrate an example insertion tool 100 operable to deliveran IOL into the eye (e.g., IOL 110 in eye 200 shown on FIGS. 2A and 2B).As illustrated, the insertion tool 100 includes a drive system 102, ahaptic optic management system 106, and a nozzle 108. The insertion tool100 may also include a plunger, which may be similar to the plunger 104shown in FIG. 1 . In some instances, The plunger 104 may be actuated toadvance an IOL, e.g., which may be similar to the IOL 110 shown in FIG.1 , within the insertion tool 100 and, in some cases, dispense the IOL110 from the insertion tool 100.

Referring to FIG. 3 , the drive system 102 includes a body 302 and alever 304 that may be pivotally coupled to the body 302. The nozzle 108is coupled to a distal end 308 of the body 302. The HOMS 106 is disposedbetween the body 302 and the nozzle 108. In some instances, the nozzle108 may be integrally connected to the body 302. In other instances, thenozzle 108 may be separate from the body 302 and may be coupled to thebody 302 via an interlocking relationship. In some instances, the HOMS106 and the nozzle 108 may be integrally formed. In other instances, theHOMS 106, the nozzle 108, and the body 302 may be integrally formed.

In some instances, the body 302 may have a slender, elongated shape. Insome instances, the body 302 may have a first portion 310 and a secondportion 312. In some instances, the second portion 312 may be at leastpartially disposed over the first portion 310. In the example shown, thesecond portion 312 includes a plurality of apertures 314. A plurality oftabs 316 formed on the first portion 310 are received into the apertures314 to join the first portion 310 and the second portion 312. The tabs316 may form an interlocking fit with the apertures 314. However, theconstruction of the body 302 of the example insertion tool 100 shown inFIGS. 3-5 is merely a non-limiting example. In some instances, the body302 may be a single unitary piece. In some instances, the body 302 mayinclude one or more cylindrical pieces. Moreover, the body 302 may beconstructed in any desirable manner from any number of components.

With reference to FIGS. 3-5 , the body 302 also includes reliefs 318,319, and 320. The reliefs 318, 319, and 320 are shallow recesses formedin the body 302 to accommodate, for example, one or more fingers of auser. One or more of the reliefs 318, 319, and 320 may include atextured surface 322 that may provide a user with an improved grip ofand control over the insertion tool 100. As shown in FIGS. 3 and 5 , therelief 318 may include texture surface 322. However, the scope may notbe so limited. Rather any, all, or none of the reliefs 318, 319, and 320may include the textured surface 322. Similarly, the lever 304 may alsoinclude a textured surface 324. However, in some instances, the lever304 may not include a textured surface.

Referring to FIG. 3 , the nozzle 108 includes a distal tip 326 thatdefines an opening 328. The nozzle 108 also includes a flared portion orwound guard 330. The distal tip 326 may be adapted to be inserted intoan incision formed in an eye, such as the incision 202 in eye 200 shownon FIGS. 2A and 2B, in order to deliver a folded IOL there into. Thewound guard 330 may include an end surface 332 operable to contact anexterior surface in order to limit a depth to which the distal tip 326penetrates the eye 200. In some embodiments, the wound guard 330 may beomitted.

In some embodiments, the insertion tool 100 may be preloaded. That is,the insertion tool 100 may include an IOL disposed therein when providedto an end user. In some instances, the IOL may be disposed within theinsertion tool 100 in an unfolded state and ready to be delivered into apatient. Having the insertion tool 100 preloaded with an IOL reduces thenumber of steps a user must perform both before delivering the IOL intoa patient. For example, a preloaded insertion tool obviates any steps auser would otherwise be required to perform in order to load theinsertion tool with the IOL. With a reduced number of steps, error andrisk associated with delivery of the IOL into a patient may be reduced.Further, an amount of time required to deliver the IOL may also bereduced. In some embodiments, the IOL may be pre-loaded into the hapticoptic management system 106.

FIG. 6 illustrates a close-up view of an example insertion tool 100 witha haptic optic management system 106. The HOMS 106 is operable to foldsthe IOL. For example, in some instances, the HOMS 106 may be operable tofold an IOL from an unstressed condition to a fully foldedconfiguration, as shown in FIG. 1 , for example. During folding, theHOMS 106 may tuck or fold the haptics 112 over the optic 114 of the IOL110 as well as fold edges of the optic 114 over the tucked haptics 112,capturing the haptics 112 and thereby placing the IOL 110 into thefolded configuration, as shown in FIG. 1 , for example.

As shown in FIGS. 3-6 , for example, the HOMS 106 is sized tocommensurate with a size of the insertion tool 100. That is, the HOMS106 has a compact size to avoid or limit an amount of obstruction to asurgeon's view while inserting an IOL into an eye. However, the scope ofthe disclosure is not so limited. Rather, in some instances, a sizeand/or shape of the haptic optic management system may be selected to beany desired size or shape. Further, while the HOMS 106 is shown disposedat the distal end of the insertion tool 100, the haptic optic managementsystem 106 may be disposed anywhere within or along the insertion tool100. In some embodiments, the HOMS 106 may be disposed between thenozzle 108 and the drive system 102.

In the illustrated example of FIGS. 3-6 , the HOMS 106 is disposedbetween the distal end 308 of the body 302 and the nozzle 108. In someinstances, the HOMS 106 may be removably coupled to the nozzle 108and/or the drive system 102. For example, the HOMS 106 may be removablecoupled to the body 302 with the use of fasteners or adhesives. In stillother implementations, the HOMS 106 may couple to the body 302 by asnap-fit engagement or any other desired method of connection. Withoutlimitation, example fasteners may include nuts and bolts, washers,screws, pins, sockets, rods and studs, hinges and/or any combinationthereof.

FIG. 7 illustrates an example haptic optic management system 106. In theillustrated example, the HOMS 106 includes a housing 702 and arms 704coupled to the housing 702. As illustrated, the HOMS 106 furtherincludes a ceiling 706 disposable on the housing 702. The housing 702forms a cavity 707 that receives the IOL 110. As illustrated, the IOL110 is disposed in the cavity 707 formed in the housing 702.

The arms 704 are pivotably attached to the housing 702 and pivot aboutrespective axes 709. In some instances, the axes 709 may be parallel toan optical axis 690 of the optic 114. In other implementations, the axes709 may have other orientations relative to the optic 114. Each of thearms 704 engages one of the haptics 112. When actuated, the arms 704cause the haptics 112 to fold over and onto the optic 114. Continuedmovement of the arms 704 further roll the IOL 110 into a U-shape, suchas the folded configuration shown in FIG. 1 . Each of the arms includesa tabs 717 extending therefrom. The tabs 717 may be utilized to rotatethe arms 704 about the axes 709. In some instances, a user may engagethe tabs 717 to actuate the arms 704. In other instances, a device,mechanism, or system may be utilized to actuate the arms 704.

In some cases, the IOL involves a base comprising a ring and hapticsextending from the ring. In these cases, an IOL base can be insertedinto an eye in a first surgical step and a separate optic can beinserted and coupled with the base at a second surgical step.Furthermore, the optic can be decoupled from the base and a furtheroptic can be inserted and coupled to the already installed base at asubsequent surgical step.

FIG. 8 is a perspective view of the arm 704. The arm 704 includes afirst end 800 and a second end 802. A body portion 804 joins the firstend 800 and the second end 802. In some embodiments, the body portion804 is generally arcuate in shape. However, other suitable shapes mayalso suitable for the body portion 804, including a generally angularshaped formed by straight portions joined at a bend, for example. A pin806 extends from the first end 800. The pin 806 is received in a boreformed in the housing 702 (discussed in more detail below), and the arm704 pivots about the pin 806. The tab 717 extends from the first end 800on a side of the arm opposite the pin 806. In some embodiment, the tab717 is formed by the pin 806 extending through pin bore 808 in the firstend 800. As explained above, the tab 717 may be used to actuate the arm704 so as to pivot the arm 704 about the pin 806. While the tab 717 andthe pin 806 are both shown at the first end 800, it is contemplated thatthe tab 717 and the pin 806 may be disposed at opposite ends of the arm.While not illustrated, the tab 717 may be disposed at the second end 802and may be used to actuate the arm 704 to pivot about the pin 806 at thefirst end 800. The arm 704 also includes a protrusion 810 extending fromthe second end 802. The arm 704 also includes a ledge 812 that projectsfrom the second end 802 on a side of the arm 704 opposite the tab 717.As illustrated, the ledge 812 projects downward beneath protrusion 810.The ledge 812 includes a haptic contact face 814. The haptic contactface 814 is operable to engage a haptic of an IOL to fold the hapticduring actuation of the HOMS (e.g., HOMS 106 shown on FIG. 7 ).

FIG. 9 shows the housing 702. The housing 702 may be made frommaterials, such as, for example, metals, nonmetals, polymers, ceramics,and/or combinations thereof. The housing 702 may have any size and/orshape. For example and without limitation, the housing 702 may be shapedsuch that all or a portion of the housing 702 may have a cross-sectionalshape that is circular, elliptical, triangular, rectangular, square,hexagonal, and/or combinations thereof. In other embodiments, all or aportion of the housing 702 may have a rectangular cross-sectional shape.

The housing 702 includes a bore 900 that traverses an entire length ofthe housing 702 from a first end 902 of the housing 702 to a second end904 of the housing 702. The bore 900 defines a path through which aplunger advances to engage an IOL and drive the IOL through the HOMS,such as HOMS 106 shown on FIG. 1 ). In some implementations, as shown onFIG. 1 , the plunger 104 continues to drive the IOL 110 through thenozzle 108 of the insertion tool 100 and expel the IOL 110 from theinsertion tool 100. In the example shown in FIG. 9 , a first portion 901of the bore 900 extending distally from the cavity 707 formed in thehousing 702 has a U-shaped cross-section. However, the scope of thedisclosure is not so limited. In other implementations, the firstportion 901 may have a cross-sectional shape that is circular, oval,rectangular, square, triangular, polygonal, or any other cross-sectionalshape. A second portion 903 of the bore 900 has a smallercross-sectional size than that of the first portion 901. Further, thecross-sectional shape of the second portion 903 is different than thatof the first portion 901. Particularly, as shown in FIG. 9 , the secondportion 903 has a circular cross-sectional shape. However, othercross-sectional shapes and sizes of the first portion 901 and secondportion 903, such as those described above for the first portion 901,are within the scope of the present disclosure. Further, in someinstances, the cross-sectional sizes and shapes of the first portion 901and the second portion 903 may be the same. The cross-sectional size ofthe second portion 903 may be smaller from that of the first portion 901because the second portion 903 may be used to pass the plunger, whichgenerally has a smaller size than a folded IOL, such as foldedconfiguration 116 for the IOL 110 shown on FIG. 1 .

The cavity 707 is formed in a first surface 908 of the housing 702 andreceives an IOL there into (e.g., IOL 110 shown on FIG. 7 ). The cavity707 includes a first end portion 910, a second end portion 912, and acentral portion 914. The central portion 914 is deeper than the firstend portion 910 and the second end portion 912 in that the centralportion 914 extends a greater distance into the housing 702. An IOL isreceived into the cavity 707 of the housing 702 such that the optic ofthe IOL is suspended over the central portion 914. A base 916 of thecentral portion 914 may conform to that of the first portion 901 of thebore 900. Thus, in the illustrated example, the base 916 has across-sectional shape that is U-shaped. The central portion 914 alsoincludes optic platforms 917 laterally offset from the base 916. One ofthe optic platforms 917 is obstructed in FIG. 9 by a portion of thehousing 702. The optic platforms 917 are raised relative to the base 916but are recessed below the first end portion 910 and the second endportion 912. The optic platforms 917 may engage a periphery of the optic114 (e.g., shown on FIG. 7 ) to support the IOL 110 in the cavity 707.

Each of the first end portion 910 and the second end portion 912 includean inclined surface 918, a haptic platform 920, a bore 922 formed in thehaptic platform 920, and an end wall 924. One of the bores 922 isobstructed by a portion of the housing 702. The end walls 924 have anarcuate shape that conforms to curvature of the haptics 112 of an IOL(e.g., IOL 110 shown on FIG. 7 ). The curvature of the end wall 924assists in keeping the IOL retained within the housing 702 in a desiredorientation. In other implementations, the end walls 924 may have othershapes. For example, the shape of the ends walls 924 may be anon-arcuate shape that conforms to a non-arcuate shaped haptic. In stillother implementations, the end walls 924 may have a shape that does notcorrespond or otherwise conform to a shape of the haptics of an IOL. Theend walls 924, in combination with the haptic platforms 920 formrecesses 926. The recesses 926 are adapted to receive the arms 704 whenthe arms 704 are in an unactuated condition.

The haptic platforms 920 of the first end portion 910 and the second endportion 912, disposed between the ends walls 924 and the inclinedsurfaces 918, define surfaces that receive the haptics 112 of an IOL 110(e.g., shown on FIG. 7 ) when the IOL 110 is in an unstressed condition.The haptic platforms 920 assist in positioning the IOL 110 disposedwithin the cavity 707 of the housing 702 in a desired orientation. Thearms 704 (e.g., shown on FIGS. 7 and 8) are supported by the hapticplatforms 920 in the recesses 926 formed in the end walls 924, with thepins 806 (e.g., shown on FIG. 8 ) of the arms 704 received into thebores 922. As mentioned above, the arms 704 are pivotable about the pins806 within the bores 922. The inclined surfaces 918 operate to lift thehaptics 112 of an IOL 110 over the optic 114 as the haptics 112 aredisplaced by the arms 704. The inclined surfaces 918 may be positionedbetween the central portion 914 of the cavity 707 and the hapticplatforms 920. A first end 928 of inclined surfaces 918 may tangentiallyalign with the central portion 914 of the cavity 707. A second end 930of the inclined surfaces 918 may be adjacent to the haptic platforms920.

With continued reference to FIG. 9 , the cavity 707 is shown disposed infirst surface 908 of the housing 702. The first surface 908 may alsoinclude one or more holes 932 formed therein. In some embodiments, theone or more holes 932 are formed in each corner 934 of the first surface908. For example, the first surface 908 includes four of the holes 932with one of the holes 932 formed in each corner 934. However, it is alsocontemplated the first surface 908 may include more or less than four ofthe holes 932.

FIG. 10A is a top perspective view of the ceiling 706. The ceiling 706protects the internal components of the HOMS 106 (e.g., referring toFIG. 7 ) from external elements. In some embodiments, the ceiling 706includes cantilever tabs 1000. The cantilever tabs 1000 may be set atany suitable angle so as to engage the arms 704 (e.g., referring to FIG.7 ) as they are actuated in the housing 702. Each of the cantilever 1000may be disposed in any suitable fashion within the ceiling 706. Thecantilever tabs 1000 may be positioned in the ceiling 706 so that eachof the cantilever tabs 1000 is positioned over a corresponding one ofthe inclined surfaces 918 when the HOMS 106 is assembled. Asillustrated, the ceiling 706 also includes slots 1002. In theillustrated example, the cantilever tabs 1000 are each disposed in acorresponding one of the slots 1002. As illustrated, the slots 1002 andcorresponding cantilever tabs 1000 may be arcuate in shape, but theslots 1002 and cantilever tabs 1000 may also be otherwise formed, asdesired for a particular application. For example, the slots 1002 andcantilever tabs 1000 may be straight or bent in form. The slots 1002each include a first end 1004 and a second end 1006. The first ends 1004of the slots 1002 extend from at or near opposing ends 1008 of theceiling 706 towards a central portion 1010 of the ceiling 706. In thepresent instance, the cantilever tabs 1000 are attached to the firstends 1004 of the slots 1002 and extend toward the second end 1006, butare not be coupled to the second end 1006.

In examples, the ceiling 706 includes one or more post holes 1012. Thepost holes 1012 may be disposed at any suitable location. In someembodiments, the one or more post holes 1012 are formed in each corner1014 of the ceiling 706. For example, the ceiling 706 includes four ofthe post holes 1012 with one of the post holes 1012 formed in eachcorner 1014. However, it is also contemplated the ceiling 706 mayinclude more or less than four of the holes 1012. In some embodiments,the ceiling 706 may also include a number of additional holes, shown onFIG. 10A as arm holes 1016.

FIG. 10B is a bottom perspective view of the ceiling 706. Asillustrated, the ceiling 706 includes a bottom face 1018. The bottomface 1018 is exposed to the inner components of the HOMS 106 (e.g.,referring to FIG. 7 ) when the HOMS 106 is assembled. The post holes1012 at the corners 1014 of the ceiling 706 penetrate through the bottomface 1018. The arm holes 1016 also penetrate through the bottom face1018. In the illustrated example, the cantilever tabs 1000 are disposedin the slots 1002 in the ceiling 706. The cantilever tabs 1000 areattached at the first end 1004 of the slots 1002 and extend toward thesecond end 1006 of the slots 1002. The cantilever tabs 1000 are notattached at the second end 1006. The cantilever tabs 1000 protrude fromthe bottom face 1018 of the ceiling 706 such that the cantilever tabs1000 are ramped from the first end 1004 to the second end 1006. As thecantilever tabs 1000 are not attached at the second end 1006, a forcemay be applied to the cantilever tabs 1000, opposite the first end 1004,to cause the cantilever tabs 1000 to deflect into the slots 1002 at thesecond end 1006. The ceiling 706 may also include ceiling ramps 1020formed in the bottom face 1018. In the illustrated embodiment, theceiling ramps 1020 slope into the ceiling 706, forming recesses 1021 inthe bottom face 1018 that accommodate the haptics 112 (e.g., shown onFIG. 7 ) as they are moved through the housing 702. Each of the ceilingramps 1020 may correspond with one of the slots 1002. As illustrated,the ceiling ramps 1020 each form an edge 1022 of a corresponding one ofthe slots 1002.

FIG. 11 illustrates a perspective view of the HOMS 106 with the ceiling706 disposed on top of the housing 702. Any suitable technique may beused to secure the ceiling 706 to the housing 702. In examples, theceiling 706 is coupled to the housing 702 through the use of anysuitable fasteners, such as pins 1100. Without limitation, suitablefasteners may include nuts and bolts, washers, screws, pins, sockets,rods and studs, hinges and/or any combination thereof. With additionalreference to FIG. 7 , pins 1100 are disposed through the post holes 1012in the ceiling 706 and the holes 932 in the housing 702 to attach theceiling 706 to the housing 702. The ceiling 706 may be positioned on thehousing 702 such that the cantilever tabs 1000 are disposed over theinclined surfaces 918 in the housing 702. In addition, the ceiling 706may also be positioned on the housing 702 such that the arm holes 1016are disposed over the tabs 717 on the arms 704, enabling engagement ofthe tabs 717 through the arms holes 1016 for rotation of the arms 704.

With reference now to FIGS. 12-16 , operation of the HOMS 106 will bedescribed in detail. For illustrative purposes, the ceiling 706 is notshown on FIGS. 12 and 13 . As depicted in FIG. 12 , the IOL 110 isdisposed in the housing 702. In the illustrated example, the IOL 110 isdisposed in the cavity 707 in order to pre-load the HOMS 106. The IOL110 is placed into the cavity 707 in a relaxed or initial state, whereinthe haptics 112 extend from the optic 114. The haptics 112 are disposedon the haptic platforms 920. (e.g., shown on FIG. 8 ). A periphery 1200of the optic 114 may be at least partially disposed on optic platform917 (e.g., shown on FIG. 9 ).

With the IOL 110 disposed in the housing 702, the arms 704 may beactuated to move the haptics 112 onto the optic 114 as shown on FIG. 13. As previously described, examples include application of a force ontotabs 717 of the arms 704 to cause the arms 704 to rotate aboutrespective axes 709. As illustrated, the arms 704 each rotate about theaxes 709 in the direction shown by an arrow 1300. As the force causesthe arms 704 to rotate and move, the arms 704 engage the haptics 112 ofthe IOL 110 causing them to move up the inclined surfaces 918. In someembodiments, continued rotation of the arms 704 folds the haptics 112 ontop of and over the optic 114. In the illustrated example, the secondend 802 of the arms 704 engages the haptics 112, thereby moving thehaptics 112 along the inclined surfaces 918 of the housing 702. As thehaptics 112 move along the inclined surfaces 918, the haptics 112 moveupward such that the haptics 112 move off the inclined surfaces 918 andon top of the optic 114 of the IOL 110.

Once the arms 704 reach the end of the inclined surfaces 918, the arms704 deflect downwards by the cantilever tabs 1000 disposed on theceiling 706, as depicted in FIG. 14 . As previously described, thecantilever tabs 1000 protrude from the bottom face 1018 of the ceiling706. At this point, the haptics 112 are folded over on top of the optic114. As illustrated in FIG. 15 , there is continued rotation of the arms704 past the cantilever tabs 1000. The arms 704 continue to push againstthe haptics 112 during this rotation causing the optic 114 to fold inupon itself as the haptics 112 are positioned above the optic 114.Additionally, as the arms 704 move past the cantilever tabs 1000, thepressure applied to the arms 704 by the cantilever tabs 1000 is releasedand the arms 704 spring upwards past the tabs 1000. FIG. 16 illustratesa top view of the HOMS 106 after the arms 704 have rotated past the tabs1000. As illustrated in FIG. 16 , the second end 802 of each of the arms704 is positioned past the cantilever tabs 1000 disposed in the slots1102 in the ceiling 706. Referring again to FIG. 15 , once past the tabs1000, the arms 704 are no longer in engagement with the haptics 112 andthe IOL 110 falls into the bore 900 in the housing 702. A drive system,such as drive system 102 shown on FIG. 1 , may then be used to dispensethe IOL 110 from the housing 702. Accordingly, the haptic opticmanagement system 106 as described herein may be used to prepare the IOL110 for insertion into the eye 200 (e.g., shown on FIGS. 2A and 2B).
